Description
Technical Field
The invention belongs to the technical field of endoscopes, and particularly relates to a periodontal endoscope.
Background
Periodontal disease is common, gingivitis and mild and moderate periodontitis can be treated by brushing teeth, using dental floss and cleaning the oral cavity, and moderate and severe periodontitis is complex, and in the case that lesions cannot be reversed, the main treatment means is to control inflammation and prevent further development of inflammation. The common means is scraping and root surface leveling, periodontal is cut through a scalpel and flap is turned over to expose subgingival root surface dental calculus, and the dental calculus is removed under the condition of direct vision by naked eyes after flap turning over.
In order to solve the above-mentioned technical problems of periodontal disease treatment, periodontal endoscopes have been invented, which are presented to treat periodontal disease without periodontal flap, so that doctors can treat periodontal disease in a minimally invasive manner. The main disadvantage of this endoscope is that the objective lens is located at the front end of the periodontal endoscope, and after the objective lens enters into the periodontal space, the objective lens is blocked by the tissue fluid, so that the image displayed on the display screen is blurred and the diseased state of the periodontal space cannot be clearly seen. In addition, in the structure, the endoscope is always in contact with a human body, and due to the fact that the endoscope is provided with precise optical components and image sensors, the endoscope cannot bear a repeated sterilization mode of high-temperature and high-pressure steaming for a long time, the common soaking or fumigating sterilization mode does not meet the sterilization requirement of dental surgery, and the endoscope is in direct contact with human tissues and blood, so that the risk of cross infection is obviously increased.
The handle of the existing periodontal endoscope only has a fixed angle, and the angle can not be adjusted in use, so that the endoscope can only carry out dental operation in one direction, and in the operation process, an operator can complete the dental operation by replacing the handles with different angles, which is very inconvenient and prolongs the dental operation time.
